Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

API 文档

1. cookie - Cookie 操作

// 设置 Cookie
cookie.set('key', 'value', { 
  expires: new Date(),  // 过期时间
  path: '/',            // 路径
  domain: 'domain'      // 域名,传入 'domain' 自动获取二级域名
})

// 获取 Cookie

// 删除 Cookie
cookie.remove('key', { path: '/' })

2. deepCopy - 深拷贝

const obj = { name: 'test', arr: [1, 2, 3], nested: { a: 1 } }
const copy = deepCopy({}, obj)

3. num - 数字运算

解决 JavaScript 浮点数精度问题。

num.add(0.1, 0.2)   // 0.3
num.sub(0.3, 0.1)   // 0.2
num.mul(0.1, 0.2)   // 0.02
num.div(0.2, 0.1)   // 2

4. reg - 正则验证

reg.Phone('13812345678')    // 验证手机号
reg.Email('[email protected]') // 验证邮箱
reg.IdCard('110101199001011234') // 验证身份证
reg.Common('abc123')         // 验证字母数字下划线
reg.QQ('123456')             // 验证 QQ 号
reg.Money('123.45')          // 验证金额
reg.imgUrl('data:image/png;base64,...') // 验证图片 URL
reg.verChinese('中文')        // 验证中文

5. time - 时间处理

// 时间戳转日期
time.toDate(1719820800, 'yyyy-MM-dd')        // '2024-07-01'
time.toDate(1719820800, 'yyyy-MM-dd HH:mm')  // '2024-07-01 00:00'
time.toDate(1719820800)                       // '2024-07-01 00:00:00'

// 日期转时间戳
time.toStamp('2024-07-01')     // 1719820800 (10位)
time.toStamp('2024-07-01', 13) // 1719820800000 (13位)

// 获取当前时间
time.getNow()  // '2024-07-01 12:00:00'

// 相对时间格式化
time.timestampFormat(1719820800)  // '昨天 12:00' 或 '07/01 12:00'

// 解析 URL 参数
getParamsUtil.getParams('http://example.com?name=test&age=20')
// { name: 'test', age: '20' }

// 获取单个参数
getParamsUtil.getParam('name', url, 'default')
getParamsUtil.getParam('age', url, 0, 'number')

// 构建查询字符串
getParamsUtil.buildQueryString({ name: 'test', age: 20 })
// 'name=test&age=20'

// 拼接参数到 URL
getParamsUtil.joinParams('http://example.com', { name: 'test' })
// 'http://example.com?name=test'

// 移除参数
